Warsaw lies in the central-eastern lowlands of Poland at approximately 52.23°N, 21.01°E, far from any moderating sea. It has a temperate continental climate with four clearly marked seasons: cold, grey winters and pleasantly warm summers, with a wide annual temperature swing of more than 22°C between the coldest and warmest months.

Summer, from June to August, is the warmest and one of the wettest times of year. July, the warmest month, averages highs around 25°C and lows near 14°C, and hot spells can push temperatures past 30°C — the record reaches 36°C. The long days bring around 16 hours of daylight at midsummer, though afternoon showers and thunderstorms are common.

Winter is cold and often overcast, with temperatures frequently below freezing. January, the coldest month, averages highs around 0°C and lows near -5°C. Snowfall is frequent but usually not heavy, and occasional cold waves from Siberia can drive temperatures down to -20°C or lower — the record low is around -30°C. Winter days are short and dark, with barely an hour of sunshine on the gloomiest December days.

Warsaw receives moderate precipitation, roughly 500–715 mm a year, distributed across all seasons but peaking in summer. July is typically the wettest month, when rain often falls as heavy thundery downpours, while late winter and early spring are the driest. A good share of winter precipitation falls as snow, which can lie on the ground for weeks. Live rainfall, humidity, and pressure readings for the city are shown in the panels above.

Spring and autumn are transitional and can be lovely — spring slowly warms after alternating cold and mild spells, while early autumn is often sunny and golden before November turns misty and damp. Humidity is high year-round, and calm winter anticyclones can bring long spells of fog alternating with crisp sunshine.
